Well I sent Dave a PM, just waiting on a reply. Guess I'd better get on selling that TA already...

RedSky, that's something I never got... It seems like my car runs slower than it should. At first I thought it was just because it was an automatic... but would it really be THAT much slower? :/ Granted, I don't think I've been bowing it up on the line enough and my tires were ****... and with these new Nittos, I expect to at least drop past 14.0. But still...

Premlor, I've heard of people on here who have done it... but I'm not sure what, if any, tune they had. I'm hoping Dave will know when he gets back with me

if you think a re-tune is expensive, you need to just back away slowly and not mod your sky

first you have to know that nitrous is not cheap. it can be anywhere from $2-$5 a pound... so if you have a 10lb cylinder, you are talking $20-$50 a fill. And if you use it a lot, you will make that 2871 upgrade look cheap. Also a bottle can be used up in a day easily.

I'd just use the Nitrous for the track, even if the setup costs me a grand [which it wouldn't, looking closer to $800], I could fill it up 20 times before it'd equal the turbo. I don't even go to the track 20 times a year.
Its not so much about the cost of the re-tune, just the fact that I'd be wasting the tune I just got -_- Kinda disheartening. I have no problem throwing 2K at it, but I'd be wasting the $600 the tune costs. I'd rather utilize it than throw it away.
I understand the turbo would be the better choice of the 2, but its not like Nitrous is a BAD setup. Inferior, perhaps, but not a bad one.

I hope Dave doesn't mind me quoting him, if so I'll gladly take it down

I've been thinking about throwing some Nitrous on the Sky, try and get it around 400HP. But I have the GMPP Tune... would I have to retune to install the Nitrous? I'd hate to scrap my tune... seems like such a waste :/
Anyway, thanks for reading, hope to hear from you soon!

Hello,

The GMPP tune is realatively mild and you could add a wet nitrous shot to the car and probably make the power that you are looking at making, but I would suggest monitoring the ECM while spraying to check for any knock. The power you are looking at making is still pretty safe on a LNF. 400hp at the crank puts about 330hp at the wheels. We feel safe with the engine up to 400 hp at the wheels.

NOS has a kit that is made for cars with electronic throttle bodies. It is nice kit and easy to setup, I would suggest it for your case.

Hope that helps,
Dave

Miller, check out the thread I posted, they say if you don't go past 75, you don't have to adjust the timing, just cooler plugs
There's a few Kappas on here that run Nitrous, I believe... if they're reading, what all have you done?

My sky had a 2871 and most bolt ons. The 2871 was a very nice kit. I ran it for over 20k miles on Dave's tune. Very safe and reliable. Full mod list in the description of the video:

It just didnt have the guts to keep up with 10 sec cars, and I wanted to be able to do that without a spending a fortune for one off custom everything, and zero resale value. IE the slicks and wheels I have for a sky sitting at home that are brand new and never mounted

No problem quoting me, anytime.

I was never into nitrous until the first time we installed a nice setup on a Solstice, it worked really well and was fun in its own unique way. Something about flipping a switch to arm the system makes you feel like something special is going to happen. It also is relatively cheap to add onto the car even when using a nice setup like we did, atleast in the short term. Like Miller mentioned, over time the cost of bottle refills will add up and surpass the cost of just doing an upgraded turbo.

So it just comes down to personal preference, how you want to make the power and how you want to pay for it. Honestly, though the thought of a stock turbo with a little shot of nitrous sounds like it would be a lot of fun and may be exactly what you are looking for. This is the kit that we have used and will probably be putting one on our little Sonic tester also:
